This code did not compile as-is, but after I commented out some things
in drivers I do not need, I managed to build something. The TBS card
now seems to be initialized, but it also broke support for my DViCO
FusionHDTV7 Dual Express card, which also uses a cx23885.

I am going to move this card to another machine that does not have any
other capture cards and repeat the process. This should make it easier
to know what the TBS card/driver is doing.

I am assuming that you are interested in using me to gather
information to update the v4l-dvb drivers so that this card can be
supported properly. Is this correct?  Please let me know what I can do
to assist.
